## 84Blocker Description
Identify or block selected 0843 and 0845 number ranges on your iPhone.
84Blocker helps UK users manage nuisance calls associated with these prefixes. Enter a number that called you and 84Blocker uses publicly available Ofcom number-allocation data to find related ranges assigned to the same provider.
KEY FEATURES
• Free Identification Mode: Label matching incoming calls as possible spam, with your choice of identification text.
• Blocking Mode: Prevent calls from selected, loaded ranges from ringing. Requires an annual subscription or one-time database purchase.
• Allow important calls: Exclude individual entries when you do not want them identified or blocked.
• On-device privacy: Number processing and call-directory preparation take place on your iPhone. 84Blocker does not upload your call history or personal information to our servers.
• Ofcom-based data: Uses publicly available UK number-allocation information to determine related ranges.
HOW TO GET STARTED
Enable 84Blocker under iPhone Settings → Phone → Call Blocking & Identification.  
Enter an 0843 or 0845 number that called you.  
Review the resulting entries.  
Tap “Set as Spam” or, after unlocking Blocking Mode, “Block Numbers” to update the call directory.
IMPORTANT
84Blocker works from telephone-number allocation ranges. It does not analyse call content or determine whether an individual caller is fraudulent. A selected range may contain legitimate numbers, so review your entries and allow any important numbers before updating the call directory.
Identification Mode is free. Blocking Mode is available through an annual subscription or a one-time purchase for the current database version. Current prices and purchase terms are shown in the app.
